Question

calculate the number of particles in 0.1 mole of calcium atom ​

Answer 1

Answer:

Explanation:

In one mole there are 6.023×10^23 atoms

In 0.1 mole there are 0.1×6.023×10^23 atoms

=>6.023×10^22 atoms

Answer 2

Answer:

According to Avogadro, one mole of any substance contains 6.023 × 10²³ particles.

Given that number of moles of Calcium is 0.1 moles

Therefore interpreting it as a ratio we get,

⇒ 1 mole = 6.023 × 10²³ :: 0.1 mole = ? ( x )

⇒ 1 × x = 6.023 × 10²³ × 0.1

⇒ x = 6.023 × 10²³ × 10⁻¹

⇒ x = 6.023 × 10²² particles

Therefore 0.1 mole of Ca atom contains 6.023 × 10²² number of particles.
